“…Thus, we suggest further studies focused on how duration of breast feeding affects the breast density. By comparing the mean age, no significant difference between those with and without breast feeding was observed ( 35 , 36 ).…”

Background:Breast cancer is one of the most common cancers and the first-leading cause of cancer deaths among women in the world. Indeed, breast cancer is ranked as the first malignancy among Iranian women. Breast density, defined as the percentage of fibro glandular breast tissue in mammographic images, is one of the known risk factors for breast cancer. According to American college of radiology-Breast Imaging Reporting and Data System (ACR-BIRADS), mammographic density is divided into four categories. Studies have shown that increased breast density is associated with significant increase in breast cancer risk. Therefore, it is assumed that breast density should be associated with other breast cancer risk factors.Objectives:The aim of this study was to assess the epidemiologic distribution of breast density of the patients in a referral center in Iran, and to evaluate the association of high breast density and breast cancer risk factors and other factors that may possibly affect the mammographic density according to previous studies.Patients and Methods:In an analytical cross-sectional study, 728 of those who had referred to Imam Khomeini Imaging Center either for diagnostic or screening purposes, participated in the study, after filling out the informed consent form, the survey questionnaire based survey assessing breast cancer risk factors affecting the breast density and related demographic features, was conducted. SPSS 11.5 software and chi-square, t-test and logistic regression tests were used to analyze the data.Results:Most of patients (75%) in categories 2 and 3 of mammographic density had a breast density of 51.9%, however, this amount was less (49.2%) in screening mammograms, while in diagnosing group it was more (51.6%). The Findings showed an increase in age, body mass index (BMI), duration of breast feeding, and also to be menopause e, unemployed and married, younger than 29 years old at first delivery, having children up to 8 and smoking are associated with less breast density. Diagnostic mammograms and symptomatic patients showed denser breasts. But density had no association with oral contraceptives pill (OCP) consumption or hormone replacement therapy or calcium and/or vitamin D consumption, age at menarche and menopause, menstruation cycle phase and family history of breast cancer. Age at the first delivery, menopausal status and parity were independently associated with breast density.Conclusions:Density distribution and risk factors prevalence is different among symptomatic patients and the diagnostic mammograms of the screened persons, hence such information should be considered in the patient managements. In order to consider the effect of marriage and parity on decreasing the breast density, basic consultations should be performed. Smokers and obese women may falsely show low breast density while they may be in high-risk group. In this study no specific phase of menstrual cycle is suggested for mammographic examinations.

“…but, the pregnancy rates are significantly lower when compared with in vivo matured oocytes in gonadotrophin stimulated cycles ( 5 ). Thus, improving the IVM success rate remains an important challenge to obtain better efficiency for fertility preservation ( 6 ). IVM has several advantages to reduce costs; avoiding the side effects of ovarian hyperstimulation syndrome and simplifying treatment for certain infertile couples ( 7 ).…”

Background:Approximately 20% of recovered oocytes are immature and discarded in intracytoplasmic sperm injection (ICSI) procedures. These oocytes represent a potential resource for both clinical and basic science application.Objective:The aim of this study was to evaluate the ultrastructure architecture of in vitro matured human oocytes using transmission electron microscopy (TEM).Materials and Methods:A total of 204 immature oocytes from infertile patients who underwent ICSI cycles were included in this prospective study. Immature oocytes were divided into two groups: (i) GV oocytes (n = 101); and (ii) MI oocytes (n = 103). Supernumerary fresh in vivo matured oocytes (n = 10) were used as control.Results:The rates of maturations were 61.38% for GV and 73.78% for MI oocytes in IVM medium (P = 0.07). However, the rate of oocyte arrest was significant between groups (P <0 .05). Ultrastructurally; in vitro and in vivo matured oocytes appeared round, with a homogeneous cytoplasm, an intact oolemma and an intact zona pellucida. However, immature oocytes indicated numerous large mitochondria-vesicle complexes (M-VC).Conclusions:Ultrastructural changes of M-VC in IVM groups emphasize the need for further research in order to refine culture conditions and improve the implantation rate of in-vitro matured oocytes.

BackgroundMassive hemoptysis is a potentially life threatening respiratory emergency and mandates immediate investigation and intervention. There is no universal consensus regarding the optimal management of these patients, and there are no large series of patients studied.ObjectivesHere we reported thirty Iranian patients who were managed with bronchial artery embolization.Patients and MethodsAll the patients had already been assessed by computerized tomography (CT) to localize and delineate the underlying etiology except 2 patients who had not undergone CT scan.ResultsTuberculosis, bronchiectasis, and lung cancer/metastasis were the most common causes, detected in 14(47%), 5(17%) and 4(13%) patients respectively. Other causes of hemoptysis including chronic bronchitis, interlobar artery aneurysm, hydatid cyst, arteriovenous fistula, pulmonary embolism, and exposure to chemical weapons each detected in one patient separately. All of them had abnormal chest CT scans, except for 2 patients who had not undergone CT scan (one with hydatid cyst and another with bronchial tumor diagnosed with bronchoscopy). Bleeding location which has been confirmed with angiography could be predicted with CT scan among 7 of 14 patients with TB, (sensitivity=50%). While this rate was 100% among all other patients with other diagnosis who had undergone CT scan.ConclusionsIn conclusion complementary to the previous studies our results have demonstrated that bronchial artery embolization remains as one of the most efficient procedures in managing massive hemoptysis, with minimal rate of complications.
